To all whom it may concem: v

Be it known that I, PETER F. HABER- STICK, a citizen of the UnitedStates of America, and resident of Wheeling, County of Ohio, and Stateof West Virginia, have invented certain new and useful Improvements inEmergency Traction Devices, of Whichthe following is a specification;

This invention relates to traction assisting devices for automobiles,and it has for its primary object to provide a simple and ineX- pensiveemergency accesory whereby the traction wheels of automobiles may bereadily afl orded traction for pulling out of ruts, mud holes and thelike.

A further object is to structurally im-' prove that class of accessoriesdisclosed in Patent No. l.144,540, granted to me on the 29th day ofJune, 1915.

In clescribing the invention in detail reference is herein had to theaccompanying drawings, in which- Figure 1 is a side elevation of therear part of an automobile showing the invention applied in workingposition;

Fig. 2 is a similar View showing the fabric strip Secured in incasingrelation to a tire;

Fig. 3 is an enlarged longitudinal section of the metal casing' andfabric-inclosing carton, showing the fabrie strip packed in the latter;and

Fig. 4 is an enlarged perspective view of an end of the fabric stripillustrating the same in the condition in which it is packed.

Referring to said drawings, 1 indicates the usual running board and 2 atraction wheel of an automobile. Removably mounted on the underside ofsaid running board adjacent to the rear end of the latter is a metalcasing 3 having an opening 4 in its rear end. Said casing is adapted toreceive therein a box or carton, as 5, in which is packed a strip 6 of asuitable fabric which is designed, when occasion requires, to have anend projected outward through said opening' 4 and through a registeringopening, as 7, in the adjacent end of the carton for attaching to thewheel 2, after which it may be wholly withdrawn from said carton bytraction movement of the wheel. As so withdrawn, the fabric strip isspread in the path of travel of the wheel, aflording a dry surface uponwhich said wheel may readily advanoe.

outer, or road engaging, surface thereof a pluralty of spaced transversecleatsconsisting of short lengths of a fiexible material,

a preferably a twist-fiber rope 8, which is incased in sheaths 9 of asuitable strong fabric. Said sheaths closely embrace the ropes 8 andeach preferably has its lateral edges disposed in overlapped relationand stitched or otherwise rigidly attached to the strip 6. Wien thewidth of the required carton 5 and casing 3 is limited to such an extent'that the latter is accomnodated by running boards l of the usualwidths, a fabric strip 6 of suflicient width to overlap the sides of theWheel-tire cannot be accommodated in open or spread condition by suchcarton. Therefore, to permit the use of a strip of the proper width toincase the sides as well as the thread of the tire and to adapt the sameto the restricted width of casing 3, and at the same time to provide forthe withdrawal of the strip in a form for assuming proper embracingrelation to the tire, I fold the opposite lateral edges of said striplon- ,itudinally over the inner, or tire-eng'aging, surface thercof, asshown at 10 in Fig. 4.

The length of the cleats aforesaid is sufliciently less than the Widthof the strip 6 that their ends fall short of the points Where thelongtudinal folds 10 occur, as shown.

The strip 6, folded longitudinally as aforesaid, is disposed within thecarton 5 in superposecl layers, as shown in Fig. 3. en its use isrequired, the carton is placed within the casing 3 which latter is thenmounted on-the running board. The uppermost end of said strip is passedoutward through the registering openings 4 and 7 and is attached to thewheel 2, as by means of suitably attached cords ll. Forward rotation ofthe wheel then acts to withdraw the strip and to wind the same about thetire. hen the strip has been Wholly withdrawn, the opposite end thereofmay be attached to the wheel, as shown in l `ig. 2, in which position atire-incasing tread is constituted. The flexible cleats presented to theroad surface creep forward and act to prevent spinning of the wheel muchin the Inanner of the creeping crosschains ofa common form of anti-skidtire chains, and a re consequently particularly effective for afordngtraction to the wheels in wet or slippery places. e

What is claimed "is- 1. An emergency traction device for Vehicles,comprsing a casing adapted for nountng in a stationary position in frontUf a fraction wheel, "afa'bfic strip of greater Width than said casing-`di`spos`ed within the latter, said strip having its lateral edges fidd &mwa-rd, n'ea-ns 'fo'r 'atta c'h ing an end bf s'a'id strip to saidwheel, and xible eleats attach ed to said strip.

-An emergency trac'tion device for Vemouting in a st atiry postin infront 'of a tract ibn wheel, a fahric strip ofgreater Width than saidcasng disposed within the letter, ;said strip having its lateral edgesfolded inwzird, mens `f'o"r `2tttaching an end of said strip to saidwheel, and flexible Cl ents attaehed to said strip between said folds,said cleats having a length a-pproximatng the Width of that portion ofthe 'strip between said iblds.
